Most red dot and magnifier setups are roommates. They share a rail, and that is about it. SIG Sauer wants the ROMEO5X-AMR Combo Kit to be more like a tag team. The red dot and the JULIET3-MICRO AMR magnifier come in one box for $499.99, and the two actually talk to each other. You won’t hear them talking, but your eyes will see the trick. This is a lot more than the usual bundle.
